See “Compostable” on a Package? Read This First
Feels like a win for the planet. But not all compostable products are created equal. The difference between home compostable and industrial compostable matters more than most people realize.
The Reality of Compostability
A compostable product is designed to break down into nutrient-rich soil. But where it composts makes all the difference.
Home compostability is a much higher standard than industrial compostability because it works in natural backyard settings—not just specialized commercial ones.
The Impact
- Consumer Confusion: Many assume all compostable products break down at home, leading to improper disposal and landfill waste.
- Environmental Misdirection: Industrially compostable products that don’t reach a proper facility act like plastic and cause pollution.
- Waste Management Issues: Cities struggle to manage packaging requiring industrial composting but ending up in the trash.
What You Can Do
- Check for trusted certifications:
- BPI Compostable—ensures industrial compostability
- Seedling Logo—European industrial compost standard
- DIN CERTCO or TÜV Austria OK Compost Home—reliable home compost certification
- Read the fine print: Labels should indicate if industrial facilities are required
- Prefer natural fiber-based materials: Bagasse, bamboo, palm leaves, or molded fiber
- Avoid bioplastics like PLA or PHA unless explicitly certified for home composting
- Test it yourself: Compost small pieces at home—if it’s still there after 6–12 months, it’s not truly home compostable
- Support transparent brands: Choose companies that explain their sustainability claims clearly
Industrial Compostability: A Limited Solution
Products labeled “industrially compostable” only break down in controlled facilities with:
- High heat: 131°F–170°F (55°C–77°C)
- Moisture and airflow management: Required to optimize decomposition
Without these conditions, they persist like traditional plastics.
The Impact
- Limited access: Most cities lack proper industrial composting facilities
- Curbside confusion: Not all programs accept compostable packaging
- Landfill contamination: Compostables in landfills don’t break down properly and contribute to methane emissions
What You Can Do
- Check if your region has access to industrial composting
- Support better municipal programs for compostables
- Choose home compostable items whenever possible
Home Compostability: The Real Deal
Home compostable products break down in natural conditions—no fancy equipment needed.
- Works at lower temperatures: 50°F–113°F (10°C–45°C)
- Breaks down in backyard bins: No special systems required
- Typical timeframe: Decomposes fully within 12 months
The Impact
- True sustainability: Breaks down anywhere, naturally
- Lower emissions: No transport needed to industrial sites
- Better awareness: Educates consumers about proper disposal and circular practices
